Updating firmware on router
Firmware refers to the programs that help a device functions normally.
However, if the manufacturer issues a major change, it could reset some (or all) of your settings.
Updating your router with factory firmware is not a “required” step. Some make all versions available, even since the device was released. Login to your router and prepare for the update Next, make sure you have a wired connection to your router.
Download the most recent factory firmware, software utilities, and documentation for your device. Connect the other end to one of the LAN ports on your router (preferably LAN port #1). After rebooting, wait another 5 minutes and run a “ping” command from your computer to see if the router responds.
Updating to the latest firmware version will help to fix bugs, avoid conflicts and add new features.
